<h4><a name = "tag_000_009_048">&nbsp;</a>NAME</h4><blockquote>
strcoll - string comparison using collating information
</blockquote><h4><a name = "tag_000_009_049">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;<a href="string.h.html">string.h</a>&gt;

int strcoll(const char *<i>s1</i>, const char *<i>s2</i>);
</code>
</pre>
</blockquote><h4><a name = "tag_000_009_050">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>strcoll()</i>
function compares the string pointed to by
<i>s1</i>
to the string pointed to by
<i>s2</i>,
both interpreted as appropriate to the 
<a href="../xbd/locale.html#tag_005_003_002">LC_COLLATE</a>
category of the current locale.
<p>
The
<i>strcoll()</i>
function will not change the setting of 
<b>errno</b>
if successful.
<p>
Because no return value is reserved to indicate an error, an
application wishing to check for error situations should set
<i>errno</i>
to 0, then call
<i>strcoll()</i>,
then check
<i>errno</i>.
</blockquote><h4><a name = "tag_000_009_051">&nbsp;</a>RETURN VALUE</h4><blockquote>
Upon successful completion,
<i>strcoll()</i>
returns an integer greater than, equal to or less than
0, according to whether the string pointed to by
<i>s1</i>
is greater than, equal to or less than the string pointed to by
<i>s2</i>
when both are interpreted as appropriate to the current locale.
On error,
<i>strcoll()</i>
may set
<i>errno</i>,
but no return value is reserved to indicate an error.
</blockquote><h4><a name = "tag_000_009_052">&nbsp;</a>ERRORS</h4><blockquote>
The
<i>strcoll()</i>
function may fail if:
<dl compact>

<dt>[EINVAL]<dd>
The <i>s1</i> or <i>s2</i> arguments contain characters outside the domain
of the collating sequence.

</dl>
</blockquote><h4><a name = "tag_000_009_053">&nbsp;</a>EXAMPLES</h4><blockquote>
None.
</blockquote><h4><a name = "tag_000_009_054">&nbsp;</a>APPLICATION USAGE</h4><blockquote>
The
<i><a href="strxfrm.html">strxfrm()</a></i>
and
<i><a href="strcmp.html">strcmp()</a></i>
functions should be used for sorting large lists.
</blockquote><h4><a name = "tag_000_009_055">&nbsp;</a>FUTURE DIRECTIONS</h4><blockquote>
None.
</blockquote><h4><a name = "tag_000_009_056">&nbsp;</a>SEE ALSO</h4><blockquote>
<i><a href="strcmp.html">strcmp()</a></i>,
<i><a href="strxfrm.html">strxfrm()</a></i>,
